Despite a lull in the recent hype that has accompanied Bluetooth several new products have been announced in the past week, writes Antony Adshead.

Norwood Systems used last week's Bluetooth Congress in Amsterdam to announce the availability of its Enterprise Mobility Bluetooth gateway.

Enterprise Mobility allows the organisation to link end users' mobile devices to existing voice and data networks and the corporate PBX phone system. Hand-off between access points is enabled as a user moves around the office. Automatic hand-off is a relatively new feature for Bluetooth - in the past a call would have been lost as a user moved between access points.

Meanwhile, 3Com has added Bluetooth USB and printing adapters to its Business Connectivity Company range, which enables users to equip desktop devices and peripherals using the wireless technology.

The system includes a facility called Connection Manage, which lets a user see all other Bluetooth-enabled devices in the office and connect to them by clicking on icons.

Bluetooth gives a bandwidth of up to 720kbps over a range of 10m, though this can be boosted to 100m using a signal booster. It operates in the 2.4GHz frequency range which also is populated by the 802.11b wireless Lan standard, giving rise to fears that it will interfere with 802.11b traffic.
